Aprilia Launches SR GT 400 & RS 457 GP Replica

© 2025, Roadracing World Publishing, Inc. From a press release issued By Aprilia

SR GT 400 is the new mid-engine GT that breaks all the rules, bringing Aprilia’s motorcycle expertise to scooters: it’s agile, responsive and stable, thanks to the Aprilia chassis and the 36 hp, 400 cc engine.

 

The SR GT 400 is 100% Aprilia:

  • powerful, light, beautiful
  • a precise ride with perfect hold and total control.
  • Electronics worthy of a sports bike.

 

City, travel, adventure: the SR GT 400 is designed to conquer both everyday tarmac roads and more remote routes.

Aprilia makes its debut in the mid-cc GT scooter segment, rewriting all the rules – as is its wont. The Aprilia SR GT 400 is the crossover that brings the design philosophy, innovation and motorcycling expertise that have made Aprilia an icon both on road and off to the world of scooters. 

The Aprilia SR GT 400 stands for performance and adventure. In traffic, it is agile and easy to manoeuvre, in mixed conditions it’s responsive, and at high speeds, it’s stable. And when the tarmac runs out, it doesn’t’t hold back. 

The new SR GT 400 accepts no half measures, aiming to establish itself as a benchmark in the category for its style and technology, as well as in all the areas that every motorcyclist looks for in a two-wheeler: thrills, fun and riding pleasure. 

The Aprilia SR GT 400 combines a strictly-engineered chassis – designed by experts who have built extraordinary motorcycles that dominate both on the tarmac and off – plus a full range of technological equipment with a powerful 400 cc, 4-valve, liquid-cooled single-cylinder engine which boasts 36 hp of power. Weighing just 186 kg in running order, the SR GT 400 is at the top of its class in terms of power-to-weight ratio.

THE APRILIA SR GT 400, A BOLD DESIGN AND CHARACTER 

The Aprilia design centre took inspiration for the shape of the SR GT 400 from Aprilia’s sports bikes and the world of off-road riding. 

The result is a stunning scooter with a strong personality that expresses real dynamism, courtesy of its sleek, sharp superstructures that echo enduro motorcycles, where every detail without a specific function has been eliminated. 

The SR GT 400 boasts a minimalist design which makes a real impact. The front end of the bike is dominated by the three-element full LED light cluster, a signature feature of 

Aprilia sports bikes. The suspended windscreen rises above, tapered vertically in pure off-road style, offering excellent protection and adjustability (five positions). 

The flanks of the SR GT are brought to life by striking slits, while the ergonomic footrests are a nod to the protective external plates of off-road motorcycles. 

From the side, the Aprilia SR GT 400 conveys a powerful sense of dynamism, with reduced overhangs and taut lines that highlight its sporty spirit. The central tunnel houses the fuel tank and connects the front and rear of the bike, giving the SR GT real motorcycle vibes. 

The grit and dynamism of the SR GT 400 is also enhanced by the design of its slim, sleek tail; the rear light cluster is fully integrated into the number plate holder, leaving it completely free, evoking the high mudguards on enduro bikes.

A 100% APRILIA CHASSIS 

The SR GT 400 is 100% Aprilia; the frame and chassis are designed and manufactured to the very highest standards, delivering precise dynamic performance and a greater feeling of safety and control regardless of the riding conditions. 

The double-cradle frame, crafted from all-new high-strength steel tubing, was designed with a motorbike-style approach. By tweaking the design and cross-section of the tubes, Aprilia’s technicians have succeeded in achieving extremely high rigidity, boosting the riding precision, front-end feel and stability. This has enabled another radical choice to be made: a reduced steering head angle which decreases the trail, for maximum manoeuvrability. This results in a safe, enjoyable ride, thanks to the perfect balance between agility and stability. 

The suspension is also inspired by the motorcycling universe: the front is fitted with a 41 mm upside-down double-plate fork with a decent 120 mm of travel. During testing, a specific calibration was developed to ensure the perfect degree of support for sporty riding, offering comfort and good absorption of bumps even on the roughest roads. 

The same applies to the rear of the SR GT 400, where a double gas shock absorber with separate reservoir takes the strain, with adjustable preload and 120 mm of travel. 

Another key goal of this project was weight reduction: the frame, engine, superstructure and alloy rims, with a new design featuring five finely- tapered split spokes, contribute to a total weight of just 186 kg in running order, resulting in a record-breaking power-to-weight ratio for the category of approximately 7 kg per kW. This also reflects positively in the bike’s acceleration, which is among the best in its class, with a time of 5 seconds in 0 to 60 metres. 

The generous braking system also features solutions that are usually found in motorcycling, with a 300 mm floating disc on the front with a radial-mounted calliper featuring four pistons and sintered pads. At the rear, meanwhile, is a 240 mm disc with a two-piston calliper. All this is supported by a dual-channel ABS system with dual mapping, either on both wheels or only on the front wheel.

CITY, TRAVEL, ADVENTURE: THE APRILIA SR GT IS READY FOR ALL ROUTES 

Riding the Aprilia SR GT 400 is a real thrill: responsive and lively when pulling away, agile and easy to manoeuvre in traffic and on winding roads, and stable at higher speeds. Furthermore, it’s always ready to venture off the tarmac, to reach less crowded places on less travelled routes. 

The active riding position and broad, double-section naked handlebars with hand guards evoke the typical ergonomics of adventure bikes, offering the best possible control, while the long-travel suspension and ample ground clearance – a minimum of 190 mm – allow riders to tackle the obstacles typical of off-road routes with ease. 

The adventurous spirit of the SR GT 400 is complemented by the Mitas Enduro Trail tyres, developed specifically for this model: measuring 120/70 on the front and 150/70 on the rear, on 16-in and 14-in rims respectively, these wide tyres feature an all-terrain tread which is suitable for all road surfaces, from tarmac to cobblestones and from dirt roads to light off-road terrain. 

Adventure is also synonymous with travel, and the SR GT 400 is ready for long distances, thanks to its capacious 12-litre fuel tank that guarantees a range of over 300 km.

BEST-IN-CLASS ELECTRONICS 

The electronic equipment on the SR GT 400 continues the Aprilia tradition and is designed and built to emphasise riding enjoyment whilst maximising safety. 

The ATC (Aprilia Traction Control) system can be adjusted to two levels of intervention, and can also be disabled, even while riding. ATC MAX and ATC MIN denote the levels of intervention. 

The braking system is supported by Bosch dual-channel ABS with dual mapping, either on both wheels or just on the front. The ABS can be disabled on the rear wheel, or the rider can even choose to disable it every time the ATC OFF level is selected. This provides the perfect setting for off-road riding: traction control deactivated and ABS active only on the front wheel. 

All parameters can be displayed and managed in a simple, intuitive manner via the instrument panel with 5″ colour TFT display and the striking graphic interface, which provides easy-to-read information in all lighting conditions as well as automatically adjusting between day and night modes. 

Aprilia MIA is Aprilia’s multimedia platform which enables the rider to connect their smartphone to the vehicle, an accessory that further extends the functionality of the instrumentation. The system also provides access to a voice assistant, phone calls and music via the handlebar controls, as well as a navigation function that enables the rider to view pictogram directions directly on the instrument panel.

COMFORT WORTHY OF GREAT TRAVELLERS 

Comfort and sportiness go hand in hand on the Aprilia SR GT 400: the riding position is comfortable and relaxed, ideal for taking on even the longest distances. Despite the 190 mm ground clearance, the saddle height is limited to 820 mm, so all riders can keep their feet securely on the ground whenever they need. 

The superior level of comfort is also enhanced by complete protection from air currents, achieved following detailed aerodynamic studies on the front end of the vehicle (which also enabled the best stability at high speeds to be achieved). The fairing, with its reduced footprint, guarantees protection in all conditions, thanks also to the option to manually adjust the height to five positions, with a total range of 70 mm. 

The keyless system comes as standard, enabling the vehicle to be started with the electronic key still in the rider’s pocket. The engine is started by pressing the button on the control panel. The underseat compartment and fuel door can either be operated using the buttons or remotely with the electronic key, which can also be used to activate the Bike Finder function – a remote vehicle recognition system that flashes all the turn signals on the bike: very useful in crowded car parks! 

The underseat compartment can hold a full-face helmet and other items, such as gloves. The central tunnel is equipped with a handy storage compartment with a USB-C socket for charging mobile devices. 

 

 

 

ENGINE: EFFICIENCY, POWER AND PERFORMANCE 

The refined chassis of the Aprilia SR GT 400 called for a cutting-edge engine to generate new levels of performance and riding pleasure. 

The 400 hpe Euro 5+ is a 4-stroke, 4-valve, liquid-cooled engine with electronic injection, inspired by a design philosophy that combines high levels of performance and readability with lightness and compactness: key to achieving superb riding dynamics. With a maximum power of 36 HP (26.4 kW) at 7,500 rpm and a maximum torque of 37.7 Nm at 5,700 rpm, the 400 hpe engine boasts a host of advanced technical solutions. 

The longer, weight-optimised connecting rod and lighter piston in stamped aluminium alloy – typically found on top-of-the-range motorcycles – help to reduce alternating inertial forces, reducing vibrations and increasing comfort, especially at cruising speeds, emphasising the SR GT 400’s suitability for touring outside the city. 

An innovative patented system called PCV – Positive Crankcase Ventilation, which consists of two blades integrated into the engine casing, reduces pumping losses and boosts power. The engine’s performance, in terms of both power and torque, benefits from a specific intake system and optimised valve lift parameters. A progressive chain tensioner contributes to quieter operation of the timing system. 

The overall efficiency of the engine is also enhanced by the optimised combustion chamber geometry based on CFD calculations, with a high-pressure injector that increases fuel atomisation and the use of low-viscosity engine oil (5W-40). The specially-

designed exhaust system, with its bold, motorcycle-inspired tailpipes, delivers a throaty, sporty roar. 

Finally, the cover of the CVT automatic speed variator features a specific design to improve belt cooling.

COLOURS 

The Aprilia SR GT 400 comes in four colourways. 

Alongside Rugged Black are two different metallic grey shades: Boulder Grey, with a matte finish and a warm tone, and Dusty Grey, with a shiny finish and cooler tones. 

These colours are paired with aluminium-coloured details, such as the passenger handles, footrest guards, exhaust tailpipes and centre console. 

The sporty black dual-layer saddle is enhanced by contrasting red/black and grey/black double stitching, whilst red details on the channel stand out against the black rims. 

The range is completed by the Aprilia SR GT 400 in Rally Replica colouring, inspired by the livery and graphics of the Aprilia Tuareg Rally, the bike which dominated in the last two editions of the Africa Eco Race, the gruelling rally raid on the historic Dakar roads in Africa. 

The matte black livery with high-impact graphics, such as the large ‘Aprilia’ lettering that runs along the entire flank of the bike, is paired with other racing details, such as gold-coloured fork stems and red shock absorber springs. The equipment is completed by a dedicated saddle, enhanced by a bold red strip on the rear, plus the Aprilia MIA connectivity system as standard.

DEDICATED ACCESSORIES AND TECHNICAL CLOTHING 

The Aprilia SR GT 400 range of accessories is designed to further boost comfort and functionality. 

In combination with the roomy underseat compartment, an ultra-resistant ABS square top box is also available to further increase load capacity. 

Characterised by a rugged, robust style with a truly adventurous spirit, the top box is fitted on the rear luggage rack, which is also an accessory, by simply and intuitively removing the passenger handles. Equipped with an airtight seal that prevents water or dust from getting inside, the spacious top box can hold a full-face helmet. It is embellished by the Aprilia logo, backrest, removable internal padding and lock with personalised key. 

The side protectors, crafted from steel tubes painted in matte black, echo the sporty lines of the vehicle, whilst protecting it from accidental impacts. 

The sporty footrests, featuring a non-slip surface and aluminium inserts, emphasise the bike’s sporty character. 

Heated handgrips ensure maximum comfort in all weather conditions; thanks to the Aprilia MIA system, also available as an accessory, the temperature level can be adjusted directly from the handlebar to three different levels, visible on the instrument panel. 

The range of accessories is completed by a leg cover, the Aprilia MIA connectivity system (as standard with the Rally Replica version) which connects the rider’s smartphone to the bike via Bluetooth, an electronic anti-theft system and an outdoor cover.
